Mechanical fastening entails placing rows of metal plates fastened to the substrate insulation with screws along the edge of the sheet. The next sheet overlaps the top of the plates and screws and is heat welded to the bottom sheet, forming a seal over the fasteners. This method offers economy as well as structural safety and works well in areas with mild winds.
Adhesives applied over the insulation boards hug the entire membrane to the substrate. The overlaps again are melted together with the heat welding machine for structural safety. Entirely glued to the roof, this system holds up well to high winds.
Ethylene propylene diene terpolymer, known as EPDM, is a synthetic rubber membrane that comes in 45, 60 and 90 mil gauges. The elastic composition of EPDM (as opposed to stiffer plastic) withstands the elements that can shorten the lifespan of other materials. Nearly impervious to the sun’s rays, ozone, acid rain and ordinary weathering, EPDM is highly flexible, lightweight and utterly indifferent to freezing temperatures and pooling water. Hail tends to bounce off rather than puncture EPDM. It’s also easily patched and maintained. Very popular precisely for the above mentioned reasons.
A fully-adhered, 60 or 90 mil EPDM system is known as the Cadillac of low-slope roof systems and can last over 30 years if properly maintained. Contact us to schedule your estimate for a premium EPDM roof today.
